Seismic structure of single steel plant what way?
1. Roof construction approach: simply the same way single-seismic construction steel plant roof and reinforced concrete columns plant.
2. column, beam structure approach: In order to control column, beam section does not appear local buckling, single frame column, beam section plate thickness ratio limits, except to be consistent with existing "Steel Design Code" GB50017 elasticity of steel relevant provisions of the stages of design, there are provisions under the table. Member web thickness ratio can be reduced by longitudinal stiffeners setting.
3. Guangzhou way between construction steel column support when cross cranes, plant unit should be set up between the upper and lower central column support, and should be added at the plant unit on both ends of the column support; 7 degrees of structural units of length greater than 120m, 8, 9 degrees of structural units of length greater than 90m, preferably in the middle third of the section setting unit between two up and down the column support. No crane factory longitudinal member section is small, does not necessarily support studs must be located in the middle. Conditional, inter-column support energy dissipation can be supported.
